Post Sealed- Infinite Baffle question

Looking to build a new house for my 2 10" subs...

Want to be a really solid sealed enclosure.

since they need very small volume.. the "sonotube" idea really caught my attention.

Although, im wondering if any of you tried to do a tube-like enclosure with wood? meaning the internal will be a cyclinder but all made out of wood?

wouldnt that be sturdier than a square sealed enclosure?

Re: Sealed- Infinie Baffle question

Sonotube is essentially heavy-duty cardboard, so if you can duplicate an enclosure like that using wood it stands to reason it would be much more rigid. The majority of the structural integrity is inherent to the shape itself.

A sealed subwoofer is not an IB though, so the title of your thread confuses me some. Those alignments are completely different.

Re: Sealed- Infinie Baffle question

This is probably not quite what you are thinking of. However I did make one out of 6mm mdf since I couldn't source a sonotube locally.

Re: Sealed- Infinie Baffle question

thx for the reply, i forgot to mention the infinite baffle part... what if i make a cylindre made of wood, (say around 12-14inch deep and i leave the back open. would that be considered an IB or would it be more of a high tuning port?

was thinkin of maybe having a removable back wall for different sonic result, maybe keep it open for movies and close it for music ? although not sure if itll be worth it

Re: Sealed- Infinie Baffle question

I don't know that a subwoofer without a back panel could be considered an IB, but I'm perhaps not the most qualified person to answer a question like that (I have little design skills). Based upon the conventional definition I don't believe it would, but perhaps someone with more experience in that area will chime in.

Leaving it open for movies would require a very good High Pass filter to prevent over-excursion with some movie content, even though mine is tuned to 13 Hz I need to look at a HPF for movies like Inception which has some extreme content around 10 Hz.
Also, it would act more like a dipole woofer - http://www.linkwitzlab.com/

For me a sealed box would be preferable as it would control the driver better.
